Mars is mighty in first Webb observations of Red Planet

First Webb observations of Mars
First Webb observations of Mars

NASA’s James Webb Space Telescope captured its first images and spectra of Mars Sept. 5. The telescope, an international collaboration with ESA (European Space Agency) and CSA (Canadian Space Agency), provides a unique perspective with its infrared sensitivity on our neighboring planet, complementing data being collected by orbiters, rovers, and other telescopes.

Webb’s unique observation post nearly a million miles away at the sun-Earth Lagrange point 2 (L2) provides a view of Mars’s observable disk (the portion of the sunlit side that is facing the telescope)...

Diet could play a role in Cognitive Function across Diverse Races and Ethnicities

Diet could play a role in cognitive function across diverse races and ethnicities
Metabolite—global cognitive function analyses flowchart. Step A: Replication and generalization analysis in HCHS/SOL of previously reported single metabolites associated with global cognitive function in BPRHS (Step A). Step B: Replication and generalization testing in HCHS/SOL of association of the metabolite risk score (MRS) constructed in BPRHS with extremes of global cognition. Step C: Generalization of single metabolite associations with global cognitive function in the Atherosclerosis Risk In Communities (ARIC) dataset. Step D: Two-sample Mendelian randomization (MR) analysis to evaluate causal relationships between the single metabolites and global cognitive function. Step E: Associations between the Mediterranean diet and single metabolites...

A New Holographic Microscope allows Scientists to See Through the Skull and Image the Brain

. A neural network in the brain of a living mouse was observed without removing the skull

The new label-free deep-tissue imaging with the wave correction algorithm retrieves the fine neural network of the mouse brain with the intact skull by focusing the light and filtering out undesired multiple scattered light waves.

Researchers led by Associate Director CHOI Wonshik of the Center for Molecular Spectroscopy and Dynamics within the Institute for Basic Science, Professor KIM Moonseok of The Catholic University of Korea, and Professor CHOI Myunghwan of Seoul National University developed a new type of holographic microscope...

The Number of Ancient Martian Lakes might have been Dramatically Underestimated by scientists

The number of ancient Martian lakes might have been dramatically underestimated by scientists

Lakes are bodies of water fed by rainfall, snowmelt, rivers and groundwater, through which, Earth is teeming with life. Lakes also contain critical geologic records of past climates. Though Mars is a frozen desert today, scientists have shown that Mars contains evidence of ancient lakes that existed billions of years ago, which could contain evidence for ancient life and climate conditions on the red planet...
